Hi, i don't know if i'm in the right place but i'm french (so i'm a little bit lost with polish) and i'm really interested by your project as i want to use it on real hardware as main os. But i have a big problem when i try to shutdown, i get a BSOD every single time (i'm using VMWare Workstation 12 Player to test it before i actually install it on a PC)

You need to use VMWare Workstation, machine should be compatible at least with VMWare Workstation 7.1.2 (as I remember).
If you want to install it on real hardware, please provide a full specs here, Longhorn is quite old system, and it's not recommended to install it on modern hardware

Thanks for the answer ! I'm just a bit confused, i need to use the 7.1.2 of Workstation Player or i need to get Workstation Pro ? And for installing it on hardware, i will try on an old pc with Windows XP so i think that's not too modern for Longhorn ahah
